Notes:
1.
The maximum numbers in this table indicate the minimum current each power rail requires in order for the FPGA to power-on successfully.
2.
The numbers in this table are based on the conditions set forth in
Table 77.3.
Quiescent supply current is measured with all I/O drivers in a high-impedance state and with all pull-up/pull-down resistors at the I/O pads
disabled. Typical values are characterized using typical devices at room temperature (TJ of 25°C at VCCINT = 1.2 V, VCCO = 3.3V, and VCCAUX
= 2.5V). The maximum limits are tested for each device at the respective maximum specified junction temperature and at maximum voltage
limits with VCCINT = 1.26V, VCCO = 3.465V, and VCCAUX = 2.625V. The FPGA is programmed with a “blank” configuration data file (i.e., a
design with no functional elements instantiated). For conditions other than those described above, (e.g., a design including functional
elements), measured quiescent current levels may be different than the values in the table. For more accurate estimates for a specific design,
use the Xilinx XPower tools.
4.
There are two recommended ways to estimate the total power consumption (quiescent plus dynamic) for a specific design: a) The
Analyzer uses a netlist as input to provide maximum estimates as well as more accurate typical estimates.
